Title: An improved 8 bits/symbol messaging scheme for g.lite.bis and g.dmt.bis
Inventor: GINESI ALBERTO
IPC: H04Q11/04
Filed: 2000-07-24
Abstract: It has been pointed out that the initialization sequence contains many elements that are limiting loop coverage. One of these is the reliability of the protocol used for messages during the Exchange phase of initialization (NG-084). In particular, the fact that the indexes of the carrier used for exchanging the messages are fixed is the main performance limiting factor. Here, we propose to make these indexes adaptive according to the frequency distribution of the channel SNR. This is known as the Exchange phase takes place after Channel Analysis, so that both transceiver can select the best 4 carriers (with the best SNR) to be used for the messages. The indexes of the 4 carriers can be exchanged using the reliable 1 bit/DMT symbol modulation.

Patent CA-2318942-A1 (CA)
Title: Program signal blocking system
Inventor: FORLER JOSEPH WAYNE
IPC: H04N7/16
Filed: 1997-12-18
Abstract: An apparatus and a method for preventing a user from bypassing a viewer blocking system using program related information, such as content ratings, included in a program signal. The present invention prevents the user from exploiting the time delay associated with detecting, decoding and comparing the program related information by switching channels to observe portions of objectionable programs before the blocking system can react. The present system comprises a processor (110) which controls the output of a selected program signal (VIDEO, VIDEO IN, AUDIO IN) in response to a determination of whether an associated program related information meets a user selected blocking criteria. The processor blocks display of a program signal when a predetermined sequence of signal channel selections is detected and then continues to block the display of the program signal at least until the determination is performed. The predetermined sequence of signal channel selections may comprise continual re-tuning of the same channel and/or switching between two channels. The present method comprises detecting a particular sequence of signal channel selections and blocking the display of the program signal upon detecting the predetermined sequence. If the predetermined sequence of signal channel selections is detected the display blocking is maintained at least until a program related information associated with the program signal is detected and a determination of the satisfaction of a user selected blocking criteria is performed.

Patent CA-2324027-A1 (CA)
Inventor: ROZENBERG IGOR
IPC: A01K87/00
Filed: 2000-10-30
Abstract: Several constraints limit the usefulness and longevity of a standard ice fishing rod. Due to the fact that most ice fishing is done in small huts, the rod must be made smaller than a standard fishing rod, thus reducing its tensile strength and leading to potential breakage. In addition, apparatus used on a standard ice fishing to indicate the presence of a fish on the line are small round plastic floatation devices that tend to freeze in the cold water, merging with ice and making the fishing experience difficult, if not impossible. This short ice fishing rod incorporates an elastic-flexible sensor-type element to act as an active bobber, able to detect and project fishing line tension and movement signaling the presence of a biting or caught fish. Under the forceful tension of the caught fish, the sensor will deflect until it touches the main mast of the rod, dispersing the load through both elements, and allowing the overall strength of the rod to be far greater than conventional ice fishing rods.

Abstract: A dense media cyclone and a classification cyclone are disclosed. The cyclone (1) comprises a body (2) having a circumferential side wall (3) extending between an upper end (4) and a lower end (5) and defining an interior space (6). The side wall (3) comprises an upper wall portion (8) and an adjacent lower wall portion (9) of traditional frusto conical configuration.  The upper wall portion (8) defines an inlet and the lower wall portion (9) defines an underflow outlet (18). A vortex finder (20) projects substantially axially into the interior space (6) and defines an overflow outlet (21). The vortex finder (20) and upper wall portion (8) define a feed zone within the interior space (6) of decreasing cross sectional area from the inlet (10) to the internal end (22) of the vortex finder (20). In addition, the wall of the vortex finder (20) tapers outwardly towards its free end and the vortex finder generally occupies a greater portion of the cross sectional area of the body than with prior art cyclones. These features of the cyclone improve cyclone efficiency by decreasing short circuiting flow both to the underflow outlet (18) and the overflow outlet (21).

Abstract: Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Use of the nucleotide sequences to mediate fertility in plants is also described. In one such method, an inducible promoter is used to regulate expression of the DNA molecule. The control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.
